I don't know the BLT treeview at all so I'm going off googled
documentation here :-) but it seems that what you need to do is to set
the -icons option, either on individual entries or on the whole
treeview to set the default for all entries. The option takes a
two-element list of Tk image names; you'll create the images using
[image create photo] whose use you can look up. Once you can display
any image at all, you can use the tkimg extension (a.k.a. Img) to gain
access to format readers for JPEG and TIFF image formats. That'll be a
simple [package require] and all should then "just work".
